When converting a GridMap to an OpenCV image with the method grid_map:GridMapCvConverter::toImage, the cv::Mat is initialized with zeros (black pixels) (here) then, only finite values are copied from the GridMap to the cv::Mat ([here](https://github

Just found out that logarithm with base of 10 doesn't have keyword in the Unary Functions, should we include it?

• The keyword of logarithm with base of 10 is not a thing while it usually refers to log(x), lg(x) or even Log(x)
• The logarithm with base 10 should be referred to lg(x) as ISO/IEC 80000 recommends.
• Exp:

// return 2.0
new Expression("lg(100)").calculate()

1. Add a reference assembly to a project, like described in the blog (e.g. https://github.com/AzureAD/microsoft-authentication-library-for-dotnet)

2. Build the sln, which builds both project and ref project

3. Pack via "msbuild /t:pack /p:nobuild=true"

Hi,

This looks like a neat repo that I'd like to try out. What is the target deployment environment you are expecting? Do you have any dependency/build/installation instructions you'd like to share?

I'm on Ubuntu 18.04 / Cuda 10.1.

Except for the very simple example, I didn't find any documentation or tutorials about this library. Can you edit one just like laspy, which allows beginners to get started quickly and make your project get more attention. You can start with simple modules, like I/O,kd-tree,octree,visualization,etc. Thank you very much!
